From the Lenten Triodion:
Saturday of The First Week
Leading us in course to celebrate the martyr's miracles. Through fasting we are cleansed from spiritual stain; from the martyr's sign and sufferings we draw courage against passions. Therefore, being enlightened by the divine grace of abstinence and by the miraculous acts of the Martyr Theodore, we are confirmed in Christ in the Faith, entreating him to grant salvation to our souls! (Matins Apostika)
